SPECIFIATION forming part of Letters Patent No. 469,120, dated February 16, 1892.

` Application filed August 8, 1891. Serial No. 402,138. (No model.)

To all whom it may concern.'

Be it known that I, JOSEPH BRUMEAUGH, of Gold Hill, in the county of Jackson and State of Oregon, have invented a new and Improved Ore-Crusher, of which the following is a full, clear, and exact description.

My invention relates to improvements in ore-crushers; and the object of my invention is to produce an efficient machine which will operate as a stamp and pulverizing machine and which may be nicely adjusted, so as to grind the ore to any desired degree of fineness.`

To this end my invention consists in certain features ot' construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevationof the machine. Fig. 2 is a plan View of the same. Fig. 3 is a broken vertical longitudinal section. Fig. 4 is a broken side elevation taken vfrom the rear. Fig. 5 is a vertical cross-section through the body and feed mechanism, taken on the line 5 5 in Fig. Fig, 6 is a broken detail sectional View of the crank-supports for the upper die-block, and Fig.'7 is an enlarged detail sectional view of the feed mechanism on the line 7 7 of Fig. 5.

The machine is provided with a substantial base 10,which supports the frame-work 11, carrying thesuperstructure of the machine, and embedded centrally in the base is a ooncave bed-plate 12, and the cavity in the base carrying the bed-plate is partially covered by the projecting plates 13 and 14, so as to prevent the possibility of any of the ground ore slushing up out ofthe bed. In the center of the bed-plate is the under die 15 of the machine, which is capable of vertical adjustment, and this adjustment may be'effected by placing metallic plates vbeneath the die. The upper die 16, which fits upon the lower die, is dovet-ailed into the block 17, which stamp projects above the bed and is provided at each end with projecting arms 18, which arms are pivoted to the lower ends of cranks 19, said cranks being secured to the shafts 20, which extend transversely across the machine above the rear end of the bed-plate; and the ends of the shafts 2O are' journaled in vertically-slid- Aing blocks 2l, which are held to move in the slideways 22 in the frame v11. The sliding blocks are connected by links 23 with cranks 24 on transverse shafts 25, which are arranged above the shafts 2O and turn in boxes 2G, carried on the top of the frame 11.

The shafts 25 are provided with upwardly extending and converging levers 27,which are curved forward and which at their upper ends are pivoted to short levers 28, th usforming toggle-joints, and the levers 28 are at their lower ends pivoted to a sliding plate 29,which is held to move vertically in the slide-way 30, which is located on the frame 11, above the central portion of the machine and on the front side, and the plate 29 is provided with a series of holes 3l, which enable it to be secured at any necessary point to the lever 32, which is arranged longitudinally upon the top of the machineframe, being pivoted at one end, as shown at 33, and the lever extends through a toothed rack 34, supported on the frame 11, and is held in a desired position in the rack by means of the spring-latch 35, which engages the teeth of the rack. It will thus be seen that by moving the lever 32 the slide-plate 29 may be moved and the levers 27 operated to turn the shaft-s 25 and thus raise the slideblocks 21 and the shafts 2O and block 17, carried by the blocks, so that by properly adjusting the said lever 32 the upper die 16, carried by the block 17, may be held the exact distance desired from the lower die 15. This' mechanism enables the ore to be ground to any desired degree of fineness.

One end ofthe block 17that is, one of the arms 18-is pivoted to a pitman 36, by which it connects with a crank-shaft 37, mounted in suitable bearings on the pedestal 38, which is arranged on one end of the base 10, and the crank-shaft isturned by a ily-wheel 39, by which power may be applied. l When the wheel is turned, the crank-shaft will be revolved and the movement of the crank-shaft will be imparted to the block 17, thus tn oving it back and forth in the cavity of the bed-plate l2, and as the stamp Will swing on the shafts 20 the upper die will have a rubbing effect as it IOO passes the lower die, and it will be seen that it will give two'grinding strokes at every revolution of the fly-wheel.

The dies are walled in by the side plates 40, the front one of which is provided with a central opening 41, the lower portion of the opening being about flush with the uppersurface of the lower die, and this opening is closed by a screen 42, beneath and in front of which is a spout 43, and when the machine is operated the movement of the block 17 will cause the pulp to slush up against the screen,

and the liner portions of the pulp will pass through and be delivered upon the spout 43; 1,

`hanger 45 which is secured to 'the feedtrough 46, said trough extending in a nearly horizontal position at one side of the machine and being supported in suitable braces 47. This'feedftrou'gh is provided with ahopper 48,which deliversinto the trou gh,and mounted transversely on the .machine-frame and on the rear end of the trough is ashaft 49 which carries a shovel 'V50 at one end, as best shown in Fig. 5, said shovel being arranged opposite the lower end of the hopper, andthe oscillations of the shovel will serve to push the ore from underneath thehopper'throug'h the feedtrough and into the inclinedspout 44.

g The inner end of 'the shaft 49 terminates in an upwardly-extending crank 5l, which projects into the path of a roller 52, 'which' is 'mounted on the upper edge of the block 17, and it will be seen 'that every stroke of the block 1'7 will cause the roller 'to strike lthe* the shovel. Instead of using the spring, however, a yoke connection may be made between the crank 51 and the block, or other suitable means may be employed to tilt the shaft 49 by the movement of the block.

The operation of the machine is as follows: The crushed ore is fed into the hopper 48, sufficient water is run through the spout 44 to Wash down and Hush the ore, and the ore is fed through the trough 46 and spout 44 in the manner described and is delivered into Y' the battery, Where, owing to the concave shape ofthe bed-platev 12, it will find its way upon the lower die 15. The movement of the flywheel 39 and crank 37 will oscillate the block 17 in the manner described, thus causing the ore to be finely ground ybetween the upper and lower dies, and from the foregoing description it will be readily understood that the machine may be adjusted so as to grind the creas line as is necessary.

Having thus described my invention, I.

claim as new and desire to secure :by Letters Patent-` 1. An ore-crusher comprising a concave bed, a die secured therein, a block carrying a die Ato impinge 'upon the lower die,said block being supported by a crank-shaft at each end, and mechanism for reciprocating the block, substantially as described.

2. An ore-Crusher comp-rising a concave bed carrying a die, a block held 'to move above the bed and provided with a 'die to impinge upon the lower die, crankvshafts mounted in yvertically-movable bearings :at each en'dvof fthe block and arranged to support the latter, and a lever mechanism for adjusting the sliding bearings, rsubstantially as described.

3. The combination, with a swinging block and the crank-shafts supporting the block, said shafts having their ends mounted in sliding blocks, of the crank-shafts connected with the sliding blocks, toggle-levers .for moving the crank-shafts, said toggle-levers having their inner ends secured to a sliding plate, and a lever for adjusting the sliding plate, substantially as described.
